To all 'ic/tom 'it may concern s' .l'e it known that l', EDWIN L.lliiiiincii, a citizen of the United States, 'and resident of NiagaraFalls, in the county of Niagara and State of `New York, have made acertain n evv and useful Invention in Machines to Facilitate the Use ofCartons; and ll declare the following to be a full, clear, and exactdescriptioii' of the saine, such will enable others skilled in the artto which it appertains tou-make and use the invention, refer ence beinghad to' the accompanying drawings, and to letters or figures otreference marked thereon, which form a part of this s iecitication.

Figure l is' a side view of the left hand portion ofthe machine, showingmechanism for carrying cartons from the packing tables. l1 ig. 2 isaside view of'the right `hand portion of the machine showing devices forsealing the cartons. Fig. 3 is a, top view of mechanism shown in Fig. l.F ig. 4c is a top view of mechanism shown in Fig. `2. Fig. 5, is atransverse vertical section through line 5-5 on Fig, l. Fig. 6, is adetail perspective View showing carton in carrier link.

Thc invention relates to mechanism signed to facilitate the packing ofbiscuit, crackers or other delicate articles in cartons and sealing thelatter, and` it. consists in the novel construction and combinationsofparts as hereinafter set forth.

The object of the invention is mainly to provide for a steady and evenmovement of` the charged carton, so that after it has been packed it eenatie-nce be placed in position for sealing, and'tvill be continuouslyand steadily moved, and at the same time held securely in such position,throughout the operation of the mechanism and will not be subjected toirregular andA rough handling, which has a tendency to break v,or injurethe articles packed therein.

. ln the accoii'ipanying drawings the figure 1 designates a 'frameworksupporting on each side an elongated packingl shelf 0r table Q, andcentrally, above the level of said table a horizontal exteiisgm of anendless cartoncari'ying belt or chain 3, said belt or band extendingthrough and engaging mechanism fo sealing the cartons as they arecarried by said holt r.llin incchanism is also provided underneath andparallel to thecarton carrier extension with an endless belt 4, at aboutthe level of the packing tables, fgihdelivei`- ing the articles to thepacking operatives, who sit at the tables, and an endless belt forreceiving and returning the pans, when such are used in the delivery, tothe source of supply. The horizontal extension 0f the carton 60 carrierbelt is shown at 3.

The framework l, has substantially parallel sides, and is of elongatedform in order to provide for extended mechanism whereby the articles arebroughtfrorn the place of supply, along between the packing tables,through the devices for sealing the flaps of j the cartons and fordrying the glue, in such i wise` as to deliver the cartons packed and`-`sealed |for casing for transportation. The carton-carrying chain Sistherefore of considerable length, and is designed to be driven* by meansof a sprocket Wheel E, geared p for the application of power. The el inyconsists of links c, provided with rollei` j `b, adapted to engagetracks a, each'of said links having upright flanges c, rising from itscross-plate o2, and extending transverse the machine, designed to holdthe carton in position for the Work to be done in connection therewith,as it is moved along the mecha nism.

rlhe carton which is employed for usegwith this-mechailiism' is designedto be --of rec tangular shape and folding` character, hav- 35 ing flapsor folding parts at its ends, these being extensions of its four walls,Of these tlaps or folds those which are upright in the carrieiaredesigned to meet or be in such near proximity that the opening betweenthem can be closed by a narrow sealing strip. 'lhe'carrier chainShaving' a horizontal extension in front of the sealing devices moveslengthwise the frame, along the track mand on the upper or direct branchthereof 95 cai ies'its links with their flanges projecting u ln thelower or return branchovfl this chain the links are arried with theirIianges depending, such lower branch being some distance below the upperbranch in the sealing portion of the machine, while in the fronthorizontal extension of the -fiaine the return track is immediatelyunder the direct track, so that the 4return branch of the chain iscarried along just under the carrying branch so as not to interfere withthe packing operation. The direct and return tracks gradualljY separateat the end of the packing mechanism, and the direct track, which is4substantially horizontal, is inteiinitted for 1w a short distance, at 6,,in order to provide for the upper portion of the sprocket wheel E,which takes the place .of the track at this point in order to engagethe'links of the chain. carrier at an intermediate point of its length.A slight downward inclination of the track just before its intermissionat 6 is designed to facilitate the engagement of the carrier links withthe sprocket wheel, this being insured by the guide bars 14,v whichengage the links on their upper edges and :keep them to the tracks.

When the goods'to be packed are placed .upon the delivery belt 4 inpans, these are carried by said belt along the track arranged therefor,at the level of the packing ltables 2 and between the same. This belt 411s provided with transverse bars placed vin series at adistance fromeach other about `the length ofa pan, and when a pan has ar- 'rived atthe end of this belt it is pushed ,onto a slideway S, which is operatedby means of the engagement of said transverse is valso bar with bevelends of the tracks of the slideway, so that these open or separate toallow the pan to fall upon the return belt 5, which rovided withtransverse bars and L 'carries t e pan back to-the place of charging.the upp'er belt with the pans.

The biscuit or other articles taken from 't the belt 4 are placed by theoperators seated "at the lateral tables in the cartons, which lili aretemporarily closed at their ends by folding the Aflaps. Each carton isthen A'placed between the `flanges of a link of the horizontal extensionof the carrier chain 3, travcling upon the upper track a, whereby thecarton 1s carried, between lateral walls 7 of the trarne, extendingalong the sides of the tracks, said walls serving to hold the flaps infolded position. The carrier chain extension in its movement toy thatportion of the machine by which the sealing 1s effected, is engaged bythe sprocket wheel E, and carries the carton between side walls G-having openings g, through which the upri ht flaps of the cartonprotrude by their e asticity, and are then held open bythe wall 'G andspreading slides z., having motion of reciprocation, in such wise thatthey are in proper position. for the `application of glue both to fingstrips are applied along the upright flaps at their adjacent edges.These strips are cut from a ribbon reel R, by means .of lnvea'ie', afterthe depending portion of each ribbon has beenv supplied withV glue uponits inner surface by means of thegluing rollers V, and has been pressedupon A the carton by the pressure plates 9. The portion K of themechanism has reciprocating motion in order that it shall have evenmovement with the chain 3 until the sealing strip has been applied.

Sometimes it Will happen that the operators at the packing table willomit to place a carton in a link of the carrier chain, and such linkwill be carried along empty. In

order to provide for this, at the place whereV lcarried along by thechain conveyer 3, pass between the heating chambers X, in engagementwith the moving pressure walls ze, and ,f

in this way the glue employed in fastening the carton flaps and'applying the sealing stripsi is caused to set and dry.

Operating mechanism for. opening and closing the flaps of the carton,applying the adhesive, and placing the sealing strips'on the carton, isdescribed in Letters Patent No. 684,788, dated October 22, 1901, andtherefore a more detailed description is not here re uired.v 1.

y this invention the sealing mechanism is provided with a carton holdingextension over the delivery belt and in close proximity thereto, so thateach filled carton can be placed by the packing operator, without cavinghis place at the table, in fixed position with relation to the carrierextension, whereb it will be 'heldtsecurely in such position w ile beingconveyed during a conu tinuous and steady movement of such carrier to,and through, the mechanism for operatingvthe flaps of the carton andsealing the same. jecting the cai-tonto change of position or handling,which has a tendency to causef the articles contained therein to bebroken or injured byA contact with its 'walls or with each otherand'thereby, as frequentlyl hap'- And this is effected Without sub-lpens with-these delicate structures, result in' many offthe cartonsuseless.

Having described the invention, what I claim and desire to secure byLetters Patent is:

- 1r In a machine for facilitating the use of cartons, a centrallongitudinal endless belt, afserics of uniformly separated claspingmeans for holding cartons in fixed lrelation to the Ibelt' and to eachother, continuous delivery meansfor material to bepacked in cartons,underand, parallel ltosanl series of nlongside said endless belt andsaid .series of means for holding cartons, und lateral ineens forholdingr cartone; lnlernl vertical. parallel walls for holding [hecartons closed above sind delivery mennev und extending tables forholding cartons .below :1nd along lside said delivery means.
